PURPOSE: The main purpose of this meta-analysis study was to identify the degree-of-effect size and the variables for the effects of manual physical therapy on myofascial pain syndrome. METHODS: This study collected six studies published between 2015.01.01 and 2019.12.31. The analysis result verified nine effect size data. The random-effect model was chosen because of the heterogeneity of the data. RESULTS: First, the full case showed the largest mean effect size of 2.297 (p < .001). Second, the size of the effect based on the fascial distortion model (FDM) intervention showed an effect size of 4.654 (p < .001). Third, the number of participants showed a 15 or less effect size of 2.612 (p > .058). The number of treatments showed a 10 less effect size of 2.844 (p > .129). The publication type showed a thesis effect size of 3.095 (p < .002). CONCLUSION: Manual physical therapy has a great effect on myofascial pain syndrome in the neck and shoulders, and that the effects differ according to the methods of intervention.

Gliomas are the most common malignant brain tumor and cause the most deaths. Manual brain tumor segmentation is expensive, time-consuming, error-prone, and dependent on the radiologist's expertise and experience. Manual brain tumor segmentation outcomes by different radiologists for the same patient may differ. Thus, more robust, and dependable methods are needed. Medical imaging researchers produced numerous semi-automatic and fully automatic brain tumor segmentation algorithms using ML pipelines and accurate (handcrafted feature-based, etc.) or data-driven strategies. Current methods use CNN or handmade features such symmetry analysis, alignment-based features analysis, or textural qualities. CNN approaches provide unsupervised features, while manual features model domain knowledge. Cascaded algorithms may outperform feature-based or data-driven like CNN methods. A revolutionary cascaded strategy is presented that intelligently supplies CNN with past information from handmade feature-based ML algorithms. Each patient receives manual ground truth and four MRI modalities (T1, T1c, T2, and FLAIR). Handcrafted characteristics and deep learning are used to segment brain tumors in a Global Convolutional Neural Network (GCNN). The proposed GCNN architecture with two parallel CNNs, CSPathways CNN (CSPCNN) and MRI Pathways CNN (MRIPCNN), segmented BraTS brain tumors with high accuracy. The proposed model achieved a Dice score of 87% higher than the state of the art. This research could improve brain tumor segmentation, helping clinicians diagnose and treat patients.

The purpose of the present study is to apply Maitland orthopedic manual physical therapy to patients to examine the effects of the therapy on the digestive system through serum gastrin tests that can identify the motility of the digestive system and dyspepsia symptoms and can provide basic data for internal medicinal physical therapy. Maitland orthopedic manual physical therapy was implemented on 20 subjects in total, with 10 in a dyspepsia group and 10 in a control group, for 20 minutes per day, three days per week for three weeks, and the following results were obtained. In the control group, serum gastrin values significantly decreased between before and after treatment(p<.01), and among questionnaire items regarding dyspepsia, those regarding epigastric pain and belching showed significant decreases in these symptoms(p<.05). In the dyspepsia group, serum gastrin values significantly decreased between before and after treatment(p<.01) and all questions regarding dyspepsia showed significant decreases in all symptoms(p<.01). According to the analysis, the dyspepsia group decreased significantly more than the control group in serum gastrin values and all dyspepsia symptoms, except for belching(p<.001). Through the present study, it was identified that Maitland orthopedic manual physical therapy can improve dyspepsia symptoms and is an effective treatment method for internal diseases, such as dyspepsia, by improving gastric motility to become close to the normal state.
